SEE ALSO: Tiny-G's Dohee confirmed for horror film 'Tunnel 3D'

During the press conference for 'Tunnel 3D' held CGV Cinema in Apgujeong, Seoul on July 16, Dohee shared, "This is the first movie I filmed, and I think I concentrated more on it than I did for dramas. However, the director and those around me helped a lot. They told me the things I am lacking, and I learned a lot from it."

She also revealed that it was awkward to not use her signature satoori, "I felt pressure now that I had to act in a Seoul accent and not satoori. Because I wasn't supposed to use satoori, I practiced how to talk in Seoul speech. I worked on it, but I'm not sure if it came out well."

'Tunnel 3D' is a 3D horror thriller film that will take viewers through the unusual occurrences that happen when a resort opens at an abandoned coal mine. Dohee joins Jung Yoo Mi, Yeon Woo Jin, Song Jae Rim, Jung Si Yeon, Lee Si Won, Lee Jae Hee, and Son Byung Ho in the film. The movie is set to premiere on August 13.
